MF 1080 Water Pump Follow Up (some questions)

Ok - followed the advice, didn't use the tractor, pulled fan off, pulled the pump, used a 3 jaw puller to get the pulley off. Bearing was totally shot.

Local parts place had a water pump in stock, matched up with old pulley (could have been 3/4" hole or 15/16" hole.

Had to order T-stat and radiator hoses...will be here in a couple days...that's ok.

Going to go put things back together later this evening...

Here is my questions:

1. How liberally do I apply the high-temp sealant to the gaskets? Instructions say a little around each bolt hole...cleaning the parts up seemed
like they applied a good bead along the whole thing...

2. The bell part of the pulley housing which goes around the stub part of the water pump...best way to describe it...was filled with what looked
to be a half inch of old grease/grime/dirt...got it scraped clean...when I press the pulley onto the shaft...do I put any kind of grease or whatever
in there? Or just assemble dry....

Thanks in advance...

2 errors for me so far:
1. When I parked it to take sheet metal off last night (before I got the advice to not run it anymore)...I had left the dump trailer behind
it....intending to use the tractor a little bit waiting for parts...
So, I thought I was being smart when I went out to get started and decided to drain the radiator to speed myself along later...then after it
drained...I realized I needed to move the tractor to unhook dump trailer in order to hook it to a different tractor.
So, I filled it up with water for the 30 seconds on run time...I guess that helped flush the radiator a little. Lol.

2. Dumb move #2. Had mounting bolts arranged on a piece of cardboard in the order I took them off. Grabbed them to bring to the bench
grinder's brush attachment to clean 40 years' worth of rust off and, without thinking, jumbled them all up. Each one is a different length. So that
will be fun later.

Thanks for the help...thanks in advance for the answers to the questions above.

When you say high-temp sealant do you mean a silicone type? I would go light on that type. Too much silicone can squeeze out on the inside as well as outside and cause problems at times. I normally use a light coating of a brush on type sealant to hold the gasket in place and #2 Permatex on bolt threads if needed; personal preference.

The inside of the pulley hub should be clean and dry. The build up you found was likely a result of leakage catching dust over time.

Be sure to support the opposite end of the shaft when you press the pulley on, you don't want to move the impeller, the bearing or split the housing.

Measure the depth of each mounting hole with a coat hanger wire, etc. Tag them and note which one is shortest (#1) all the way though to longest (#5 maybe or however many there are). Arrange your bolts in order say #1 to #5 as well. Hopefully that should work without bottoming anything out. Check hole depth to bolt length before final assembly of each one. Good luck with your project.

Awesome idea. Thanks!

Just what I was going to say!

Very important detail. The pulley must be pressed carefully, kept straight, and to the same position it originally was set. No hammering allowed!

Not having a ton of luck getting the pulley pressed all the way on...about an inch from the finish point.

Any tips to get it all the way.

Well. Solved the problem.
Never had a proper hydraulic press, usually a hydraulic jack a couple plates and a tractor or hay barn post or the very large vise has worked when needing to press things. That would not work for this pulley.

Was going to cash my harbor freight gift cards in this morning but didn?t particularly feel like going through the process of putting it together...so I checked craigslist.

$65- 20 ton press- delivered to the house, ready to go.

Pulley pressed on 3 min after he left the driveway.

I never end up buying one because I have gotten around it and figure I only need it 3-5x per year. But. Now I have one.
